In English, if someone asks, for example
Who is here?
one can respond with an object pronoun, like “me”, “her”, “us”, etc.
In Spanish, if someone asks
¿Quién está aquí?
One can say “Yo estoy aquí” in response. However, if there’s a really long question, e.g.
¿Quién está muy alegre y quiere tocar el piano al medio día?
this form of response is weird—one would never say “I am very happy and want to play the piano at noon” in response in English. They would just say “me.”
How can I respond? Could I say “me?” If I don’t want to say the full “Yo estoy aquí”, what is the short way to respond to this question, if there is one?
